If players die within the cooldown period (default 600 seconds), then 10 seconds (default) is added to their respawn timer after each death, and the cooldown period restarts. 

If players stay alive past the cooldown period, respawn timer penalties are reset to 0.

Additionally, there is an option to scale the penalties by rank. The higher rank you are, the less time is added for each death. This is on by default and can be configured under the Conflict Game Mode prefab under the SCR_ScalingRespawnTimerComponent.
